Slayetry is the act of slaying, poetically(causing all around you to be impacted emotionally or aesthetically).
Kelly's yellow easter dress at church, was total Slayetry.
Even the pastor could not help but be moved.
Committing slayetry effectively, without incurring any damage(I.E. none others to outshine you; haters silent). This includes chip damage( even when the haters come, it's not enough to knock you off your pivot).
All over the course of your round of Slaying.
I.E a "perfect win"
Mya: "Did you see Ivanka's outfit the other day at the restaurant the other night?"
Aaliyah: "She's committed Flawless Slayetry the last three times i have seen her!"
Mya: "I'm sure having her boyfriend pay for eveything helps."
